Geological Summary

The 5 x 6 km Nila Island in the Banda Sea is comprised of a low-rimmed caldera breached at sea level on the south and east, with a 781-m-high youthful forested cone. Phreatic eruptions from the dominantly andesitic volcano, also known as Laworkawra, have occurred from summit vents and flank fissures in historical time. A 1932 eruption from a fissure that extended from the summit to the SE coast produced heavy ashfall that forced abandonment of Rumadai village.

Nila Island, viewed here from off its northern coast, is the emergent summit of a stratovolcano that rises 3700 m from the Banda Sea floor. A submarine vent is located off the north flank immediately west of the small island of Nika. Gas bubbles were observed along the rim of the submarine cone in 1932, when an eruption occurred from a fissure extending from the summit to the SE coast.

A fumarole plume (right-center) rises above the steep SE slopes of Nila volcano, also known as Laworkawra or Lawarkawra. A remnant of the rim of a 5-km-wide caldera forms the forested slope at the left. The 781-m-high summit above it is a post-caldera cone that fills much of the caldera and extends to the sea at the right. Phreatic eruptions from Gunung Nila have occurred from summit vents and flank fissures during historical time.

The DECADE portal, still in the developmental stage, serves as an example of the proposed interoperability between The Smithsonian Institution's Global Volcanism Program, the MAGA Database, and the EarthChem Geochemical Portal. The Deep Earth Carbon Degassing (DECADE) initiative seeks to use new and established technologies to determine accurate global fluxes of volcanic CO2 to the atmosphere, but installing CO2 monitoring networks on 20 of the world's 150 most actively degassing volcanoes. The group uses related laboratory-based studies (direct gas sampling and analysis, melt inclusions) to provide new data for direct degassing of deep earth carbon to the atmosphere.

WOVOdat is a database of volcanic unrest; instrumentally and visually recorded changes in seismicity, ground deformation, gas emission, and other parameters from their normal baselines. It is sponsored by the World Organization of Volcano Observatories (WOVO) and presently hosted at the Earth Observatory of Singapore.

Middle InfraRed Observation of Volcanic Activity (MIROVA) is a near real time volcanic hot-spot detection system based on the analysis of MODIS (Moderate Resolution Imaging Spectroradiometer) data. In particular, MIROVA uses the Middle InfraRed Radiation (MIR), measured over target volcanoes, in order to detect, locate and measure the heat radiation sourced from volcanic activity.

Using infrared satellite Moderate Resolution Imaging Spectroradiometer (MODIS) data, scientists at the Hawai'i Institute of Geophysics and Planetology, University of Hawai'i, developed an automated system called MODVOLC to map thermal hot-spots in near real time. For each MODIS image, the algorithm automatically scans each 1 km pixel within it to check for high-temperature hot-spots. When one is found the date, time, location, and intensity are recorded. MODIS looks at every square km of the Earth every 48 hours, once during the day and once during the night, and the presence of two MODIS sensors in space allows at least four hot-spot observations every two days. Each day updated global maps are compiled to display the locations of all hot spots detected in the previous 24 hours. There is a drop-down list with volcano names which allow users to 'zoom-in' and examine the distribution of hot-spots at a variety of spatial scales.
